For the first time ever, a special sale product from Tokyo notably uses kelp produced overseas. In a marked departure from traditional reliance on domestic kelp, suppliers are now sourcing their ingredient from a foreign country. The news has gained traction due to Japan's deep cultural connection with kelp, a widely used ingredient in Japanese cuisine. The date and specific location details are yet to be released.

In Japan, there is a strong preference for domestic products, especially when it comes to local cuisines. This news is considered significant since it indicates a drift from the long-standing practice. Consumption of foreign goods can often be seen as a matter of national pride and indicative of changing cultural norms.

In contrast, the US and EU have a diverse food industry with different raw materials imported from around the world. It is very common to use imported ingredients, and people generally have less preference for domestic products compared to Japan.
